The cops part sux.
My favourite road travels beside the Otonoabee river between Peterborough and Lakefield. It was freshly paved a few years back and since it follows the river, it has tons of turns with various radii. Better yet, since it is beside the river, there are very few blind corners, so you can go full out seeing that the road is clear of opposite traffic, pedestrians, cyclists etc. Just one thing, if you go off the road, the experience can be quite "dampening"....
